SOURCE: O2 sensor and EVAP issues

P0446 is Aux Emission Control
P0132 Fuel Air Metering

The Evap Canister is located in the fender well, if I am not mistaken and the B1S2 is the O2 sensor is the second O2 sensor on the left side of the engine if your looking at it from the front of the motor.

SOURCE: i have error codes p0156 p0161

  Check the wire harness near the top of the engine in the rear. They were good for rubbing through on the trans fill tube bracket. Judging by the code you have 4 sensors. you would be interested in the drivers side rear sensor.

SOURCE: check engine light

this is very common on these. the upper intake seals leak and should be replaced. It is not a noticable vacuum leak and is usually worse when the engine is cold. It is not a very difficult job to do

SOURCE: Diagnostic Codes p0171 bank 1, and p0174 bank 2 (too lean)

Those codes are for the oxygen sensors, lean fuel mixture on both banks. Change them, problem with stalling and rough idle should go away.

2004 freestar dies when stopped and has codes p0171 and p0174 what could it be?


P0171 system too lean bank 1
P0174 system too lean bank 2

You aren't getting enough fuel to keep car running and the system shuts car down

P0171, P0174


I believe these at left and right bank lean codes, for both bank to go lean check under hood for vacuum leak, in or around the intake, with engine running at idle you should be able to hear hissing of vacuum leak, fix leaking vacuum, clear codes.

Engine check light on error code 1 is P0171 system too lean bank 1 error code 2 is P0174 system too lean bank 2


P0171 system too lean bank 1
P0174 system too lean bank 2
links to information on the codes

it means that the O2 sensors in your vehicle detected a lean condition in their respective banks. this could be caused by a dirty MAF (mass air flow) sensor or a vacuum leak downstream from the MAF sensor

sometimes you can clean the MAF with electronics cleaner or brake cleaner but be sure to take it off the vehicle first. be careful not to damage the MAF while spraying the cleaner, and allow it to dry completely before installing it on the vehicle.

We have a 99 ford ranger 3.0L flex fuel and it is throwing system too lean bank 1 & bank 2 codes, P0171, P0174...we have replaced 02 sensors, mass air flow sensor and have paid for 2 diagnostic tests...


Your paid people have never diagnosed ,the lean condition you have.

If it points to MAF Sensor,new or old,why did they stop
testing. Don't have a Data Base they subscribe to?
Don't have that kind of diagnostic experience?

Need to see the system on paper, and follow a trouble
chart or use common sense.

In the end, all you probably have, is a vacuum leak somewhere

Check all the bolts holding the plenum, and anything else concerned with air intake. Too much air means weak mixture.

Failed OBDII Diagnstic trouble codes P0761 and O1744 What does this mean?


code P0761-
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid 3 valve
- Shift solenoid 3 valve harness or connectors
- Shift solenoid 3 valve circuit is open or shorted
P0761 FORD Description Shift solenoid valve 3 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When is the code detected? The P0761 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off code O1744- is not a code these are the ones I have found that come close

Ford windstar check engine light comes on after stopping when starting to get moving again shows p0171 & p0174 codes why??


P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks. P0174 OBD-II Trouble Code


Technical Description

System Too Lean (Bank 2)


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

Thanks.
